Prerequisites for working with CPC images

• HCD uses BCPii (Base Control Program internal interface) to query the image (partition) attributes from the Support Element (SE) of the selected CPC. In order to get the partition attributes, the following requirements must be met:
  • The BCPii address space (HWIBCPII) is active and ready to handle BCPii requests.
  • The local and remote support elements (SEs) are enabled for BCPii communication (cross-partition authority must be enabled for each CPC that is queried).
  • The BCPii community name must be defined on the SE for the local and each remote CPC that is queried.
  • The managing user ID must get the authorization to perform the BCPii calls for the target CPCs / images.
• The target systems must have a TCP/IP connection to the managing system. For more information, refer to Appendix E. Establishing the host communication.
• The user must provide a connection table for the target systems which contains the TCP/IP login data.
• There must be a user ID on each target system that has the authorization to perform dynamic activations and corresponding system commands and that has access to the active production IODF.
• An HCD dispatcher must run on each of the target systems that allows directing incoming remote HCD requests to the local HCD versions.
• The required security setup for using this function is described in Defining RACF profiles and Access to HWI.* profiles.
